Well, the card_num schema node is going to be a child, most likely, of a
mapping schema node. You could put the validator there.

Something like this maybe:
class CreditCardSchema(colander.Schema):
card_num = colander.SchemaNode(colander.String())
exp_month = colander.SchemaNode(colander.Integer(),
validator=colander.Range(1,12))
exp_year = colander.SchemaNode(colander.Integer(),
validator = colander.Range(2013,2014))
@staticmethod
def validator(form, value):
if value['exp_year']==2013 and value['exp_month']<6:
raise(colander.Invalid(form, u'Wrong year and month'))
elif value['exp_year']==2014 and value['exp_month']>6:
raise(colander.Invalid(form, u'Wrong year and month'))
class LoadCreditCard(colander.Schema):
... all the other stuff goes here ...
credit_card = CreditCardSchema(validator=CreditCardSchema.validator)
x = LoadCreditCard()
x.deserialize({'credit_card':{'card_num':'xxxxx', 'exp_month':'12',
'exp_year':'2014'}})

Hello Pyramid community,
I was wondering if any of you have used Colander and could help me
out with a validation question. I want to validate a credit card schema:
{'card_num': 'xxxxxxxxxx', 'exp_month': 12, 'exp_year': 2013}
The problem is that the validation for the expiration month will
change depending on the year. Is there any way to pass in other
nodes to the give nodes 'validation' method? OR is it possible (or a
good practice) to throw a colander exception in an 'after_bind' method?
Thanks!
